The Basel Committee on Banking Supervision published its Basel III monitoring results as of Dec. 31, 2025, finding that risk based capital and leverage ratios for large internationally active banks remained broadly stable from June 2025. Their average Common Equity Tier 1 ratio under the current framework held at 13.9%, while full implementation of the final Basel III standards would raise Tier 1 minimum required capital by an average of 2.2%. The corresponding impact was 1.8% for global systemically important banks and 0.7% for other banks. For Group 1 banks, the 2.2% capital impact reflected a 3.2% increase from risk based requirements, driven mainly by the output floor and market risk, partly offset by a 1.0 percentage point reduction in leverage ratio requirements. Banks reported an aggregate capital shortfall of EUR 1.4 billion under the fully phased in framework. The average Liquidity Coverage Ratio for Group 1 banks rose 1.7 percentage points to 136.6%, while the Net Stable Funding Ratio declined 0.6 percentage points to 123.3%. All 149 banks in the sample exceeded the 100% minimum for both liquidity measures. The estimates assume full implementation without transitional arrangements, management responses or Pillar 2 requirements.
